Summary0005146: TJvTreeNode.SetChecked does not work when user changes node state
DescriptionIn additional information i have add my solution.

The example of this problem is:
First i do SelectAll procedure (listed below) - check all nodes in code.
Next, the user will disable some checkboxes and after that, if i execute my SelectAll procedure, checkboxes disabled by the user wont be checked.

procedure TForm1.SelectAllClick(Sender: TObject);
  I: integer;
  for I := 0 to JvTreeView1.Items.Count - 1 do
Additional InformationI think the problem is in procedure TJvTreeNode.SetChecked(Value: Boolean);
in first line: "if Value <> FChecked then"
FChecked is variable which is not refreshing on user actions.

Changing this line to: "if Value <> GetChecked then" solves the problem.
TagsNo tags attached.

i have provided minimal example - first click "select all" button to check all nodes (all three nodes will be checked correctly). after that, click on any checkbox to uncheck it. finally, click "select all" button again (unchecked nodes won't be checked...)
